Unmanaged Switch Lacks Configuration Interface | Generated by AI
Question: My Mercury 5-port 1000Mbps switch (model 5G105C, dark color, 5V 0.4A) does not act like a router and has no IP address for configuration. Is it not accessible via 192.168.2.1 or similar addresses?
Answer:
Your device is a Mercury (or likely rebranded Mercusys) 5-port Gigabit Ethernet switch, with a model similar to SG105C, SG105M, or MS105G. These are unmanaged desktop switches designed for simple plug-and-play operation.
Key Characteristics
- Unmanaged switch: It has no web interface, no configuration page, and no assignable IP address. Unlike a router (which typically uses addresses like 192.168.1.1, 192.168.0.1, or 192.168.2.1 for setup), an unmanaged switch operates at Layer 2 of the network. It simply forwards Ethernet frames between connected devices without any management features.
- No IP address: The device itself does not obtain or use an IP address for access. You cannot log in to it via a browser or configure settings like VLANs, port mirroring, or QoS.
- Power specs match: Many similar models (e.g., Mercusys MS105G) use a 5V power adapter (often around 0.6A, but 0.4A is close and common in variants).
- Behavior is normal: It “doesn’t act like a router” because it is not a router—it’s just a basic switch to expand your network ports and connect multiple devices (e.g., computers, TVs, printers) at Gigabit speeds.
What You Can Do
- Connect your main router to one port on the switch.
- Plug other devices into the remaining ports.
- Everything should work immediately—no setup required.
If you need advanced features (e.g., a web config page), you would require a managed switch instead.
